        DataTable <span class="subitem">Lazy</span>
    </ui:define>

    <ui:define name="description">
        DataTable has built-in support to deal with huge datasets. In order to enable lazy loading, a LazyDataModel needs to be implemented
        to query the datasource when pagination, sorting, filtering or live scrolling happens. This example uses an in-memory list to mimic a real datasource like a database.
        In a real application, loading should be executed with the query built using the information passed to the load method.
